METAL -WALL TILE FASTENING Application filed October 8, 1831. Serial No.567,652.

My invention relates to metal wall tile and its principal object is toprovide a novel means for mounting the odd shaped tile's such as thebase and cap pieces. 7 7 It is'also an object of this invention toprovide a novel, fastening means operating in conjunction with saidtile.

Otherand more specific objects ofthe invention will appear as thedescription proceeds in connection with the accompanying drawing whereinthe preferred form of the invention is shown. It is to be understood,however, that the disclosure is illustrative only and is not to be takenas limiting the invention except in so faras it is limited by theclaims;v i

In the drawinge F ig. l is asectional view taken in perspective throughthe wall showing my invention as applied thereto; p -Fig. 2 is anenlarged fragmentary section illustrating the fastening means; i p

Fig. .3 is a perspective view showing the interior of two cap tile thatare used to cover a protruding or exterior corner; and- Fig. 4 is aperspective view of the base tile.

Referring now in detail to the drawing, the roof wall is indicated at 5,the mounting board 6 is secured thereto in suitable fashion as forexample by nailing. The mounting board 6 is preferably made up of sheetswhich sheets are in the usual wall 44 inches high and 28 inches wide.These sheets are used as a base on which to secure the fastening clips 7thatare arranged in rows to receive the tile and lock them in place. Theordinary wall tile used between the top and base is illustrated at 8 and9 and usually consists of a rectangular sheet having all four edgesturned toward one side to form the mounting flange, theseiedges beingbent toward each other so as to form an angle of somewhat lessthan 90with the general plane of the tile. 7 Y

The base tile 10 and he captile 11 have three side edges turned in inthis fashion as indicated for example in Figs. 8 and 4. The base and captile however, must necessarily have a portion thereof alongone edgeturned out of line with the main body portion if a smooth joint is to bemade with the I wall and fioor. The turned out portion is indicated at12 on the base tile, and this turned out portion has the flange 13 whichforms an abutting wall for the tile 14. Similarly the cap tile is curvedas indicated at 15 and has the downturned flange. 16 contacting with theplaster wall so that the finishing coatof' plaster 17 can'be placeddirectly on top of the cap tile in finishing the joint.

Now in order that these tilemay readily fit the same securingclips 7that hold the standard tile it is necessary to providesome meansfor'engaging one'end 'of the clip.

I provide-as a means of accomplishing this the piece 18 which as shownmostclearly in Fig; t extends transversely across the tile substantiallyparallel with the edge '19 that is directly opposite the out-turnedportion of a base or cap tile. This-striplS has the flange 20 thereofbenttoward'the edge 19 so as to form an angle with the plane of the tileof somewhat less than 'The strip I is secured to the tilebodybefore'enameling in any suitable manner such as by spot 3 welding.

Bythis means I am able to provide adequate securingmeans for the baseand cap tile in a simple economical manner. Furthermore the strip 18 byreason of its position adjacent the out-turnedportion of the tile servesto reenforce the tile at the point where it ismost liable to besubjected-to heavy stresses and thus acts as a protector against thetile being bent out of shape. The provision of this mounting means doesnot in any way prevent'the formation on all 7 four edges of the tile ofthe abutting" flanges which gives smooth roundedshoulders Where I thetile meet and'thus avoids sharp corners from which the tile normallymight readily become chipped. i

Now in Fig. 3, the cap tile 21 being a corner cap has a special formwhich necessitates the provision of two strips 18 inorder thatthe samemay be readily mounted upon any exterior corner. It is to be noted thatthis cap tile is curved along the edge 15' and also along the edge 22and is still provided with the peripheral flange to provide the smoothabutting surface for adjacent tile or for the Wall.

The strips 18 arranged at right angles to each other enable the tile tobe applied to vertically running clips whether the corner portion 22 islaid in vertical position or horizontal posit-ion.

I find also that in order to secure proper attachment of the tile thatcertain essential features must be provided in the clips 7. If theportion 23 of the clip 7 is not made of the right relative shape withrespect to the flange 19 of a tile, serious difficulty is en counteredin obtaining a'fastening, of the tile without chipping of the enamelthereon at the corner 24.

I find, therefore, that in order to obtain a good fastener, a relativelylong shank at 25 should be provided and this should extend substantiallyat right angles to the wall through which the clip is secured. Theportion 23 of the clip should be long and substantially straight soasto' provide a long sloping surface for the edge of the flange 19 tocontact. Also, preferably the angle of this sloping portion with respectto the flange 19 should be a fairly acute angle suchfor example as lessthan 30. It is necessary, however, that the slope of the portion 23 withrespect to the board wall be suflicient to permit it to fleX slightlyunder the pressure of the edge of the flange 19 in order that a securefastening may be obtained. The angle of the portion 23, therefore, withrespect to the wall 6 should be substantially the same as the angle ofthe flange 19. The free end ofthe clip is. bent inwardly toward thestraight por: tion 7 thereof as shOWn in Fig. 2. This end serves as astop against the wall board for the clip. 7

From the above description, it is believed that the construction andadvantages of this device will be clear to those skilled in this art.
